I have a nice nickel 4" m 19-4 it is like new. original nickel.
While out shooting with my son who has a 3" Taurus 357 my 19 would blow back a primer with 125 mag and 145 Hornaday mag. In one chamber only. It needed a rubber mallet to open. It will always do it with that ammo. 38 standard, 38+p and +p+ both 110 and 147 are fine. 158 gr mag is ok so far. It is not a stuck case but a blown back primer All factory ammo. The Taurus had none of these issues. What do you think?
